Change File Permission at run time

Question

I have two users in a group.

Users:
   1) apache
   2) data
Group
   1) apache

I have three directories. The directory structure of that three directories are like below.

drwxrwx--- 10 data    apache 4096 Aug 21 14:30 Data
drwxrwx--- 10 data    apache 4096 Aug 21 14:30 App
drwxrwx--- 22 apache    apache 4096 Aug 22 12:04 www

I have a copy program in App directory. It will copy a file from Data directory to www directory. After the copy process over, the copied file are in the mode of below.

----r-----  1 apache apache   35003 Aug 22 11:47 wT89TQsATjE.txt

But I want to be that file permission as like below after the copy process.

-rw-rw----  1 apache apache   35003 Aug 22 11:47 wT89TQsATjE.txt

Could I change the mod of the file to be read as user and group after that copy process automatically?

Answer 1

Depending on the permissions before the file is copied, you might copy them with cp -a, which will preserve permissions. This of course means, that your file has to have the permissions -rw-rw---- set before copying.

As a second option, why not change the permissions of the file right after copying:

chmod 660 $copiedFile
